1. Burgess reagent is easy to oxidize, and at the same time it is also very sensitive to moisture, and should be used immediately after fresh preparation. 2. Burgess reagent is a highly efficient dehydrogenation reagent that can be used for the preparation reaction from formamide, nitroalkane compounds to isocyanide, nitrile and oxide nitrile compounds. In recent years, the biggest use of Burgess reagent is to realize the cyclic dehydrogenation reaction of hydroxyamide and sulfamide to obtain the corresponding heterocyclic compound. The chiral center attached to 2-C in thiazoline is prone to epimerization, so much so that most cyclic dehydrogenation reactions of hydroxysulfamides produce enantiomer mixtures. However, under the induction of Burgess Reagent 1, hydroxysulfamide will obtain chiral monomers with high stereoselectivity of 96% yield and greater than 94% enantioselectivity. Compared with Burgess Reagent 2 itself, the reagent 1 obtained by ligating Burgess reagent with polyethylene glycol can induce the preparation of zoline and thiazoline compounds at a higher yield. Induced by dehydrogenation reagent 2, hydroxysulfamide can be converted to thiazide at high yield, which is a higher yield than the Mitusnobu reaction. |
